The, invention .is illustrated inwtln's application as applied to amachine of .the type illustrated and described in the patent'toFoothorap, No. 1,904,127dated April '18, 1933, andv many of "the partshave substantially the same construction asthe corresponding parts ofthe machine illustrated and describedin said patent. The machineillustrated in the present application comprises a 'pla'te'n frameprovided with side rails orbars2 connected by transver'se bars, 'o'necrwhich 'is indicated at llfand a substancanyonlaten 6 mounted forvertical movement-in said frame. Upon the side rails of the -pl'atenframe is supported-aline space frame movable forwardly and rearwardlyi'on said rails tolin'e space the type carriage with relation to theplaten. The line space frame comprises side brackets or bars 8 connectedby front and rear rails of which the rear rail only is shown in thisapplication and is indicated at It. The line space frame is providedwith wheels or rollers 12 which engage respectively the upper edges ofthe rails 2 of the platen frame to enable the line space frame to bemoved readily over the platen frame.

The mechanism for moving the line space frame comprises a shaft 14rotatably mounted in bearings formed on said frame, the shaft extendingsubstantially parallel with the front and rear rails of the frame. Uponthe shaft are fixed gears l6 which mesh with the teeth of racks 18secured to the side rails 2 of the platen frame, The shaft is given apredetermined angular movement in a counter-clockwise direction, Figs. 6and 8, at the end of the return movement of'the carriage to impart aline space movement to the line space frame.

The type carriage, aportion of which is illustrated in Fig. 1 andindicated at 20, is provided with wheels or rollers 22 which engage theupper edges of the front and rear rails of the line space frame so thatthe carriage is movable transversely of the machine along said rails toimpart forward and return movements to the carriage. The carriage isconnected by a flexible band 23 to the usual spring drum 25 which tendsconstantly to draw the carriage in a right hand direction across themachine.

The machine embodying the present invention is preferably provided witha key and carriage controlled automatically operating mechanism forimparting return movements to the type carriage as is shown anddescribed in the above Foothorap patent.

The mechanism for turning the shaft l4 to actuate the line space framecomprises a wheel 26 attached to one end of said shaft and having aseries of fine teeth on its periphery which are engaged at intervals bya pawl 28 pivoted at 30 on a pawl carrier 32 mounted to turn on theshaft. A pawl actuating bell crank 34 is also pivoted on said shaft andis provided with a pin or stud 36 on one arm thereof engaging in a slot38 in the outer portion ofthe pawl. The pivotal movement of the pawl 28with relation to the pawl carrier 32 is limited by means of a pin 40projecting from the pawl carrier and engaging in a recess 42 in thelower portion of the pawl. The pawl carrier and the pawl actuator areacted upon respectively by coiled springs 44 which tend to swing the.carrier and actuator in a clockwise direction (Figs. 6 and 8). The pawlcarrier and pawl .actuator are. normally held substantially in theposition shown in Fig. 8 with the pawl in engagement with a stop.46 onthe line space frame and the pawl is thereby held out of engagement withthetoothed wheel 26.

In actuating the toothed wheel, the pawl actuator 34 is swung in acounter-clockwise direction Figs. 6 and 8. During this movement of theactuator the pawl is first engaged with the toothed wheel and the pawlcarrier and toothed wheel are then turned with the pawl actuator untilthe movement of the pawl is arrested. The movement of the pawl isarrested to limit the line space movement by means of a stop pin 48-mounted on a bracket 50 attached to the line space frameand "arrangedto engage the forwardside of the pawl as shown in Fig. 6. The engagementof thepawl with the toothed wheel 26 after the movement of the pawl isarrested, locks the line space frame in position.

The pawl actuator is swung in counter-clockwise direction Figs. 6 and 8to actuate the shaft I4 to impart a forward movement to the line spaceframe just before the completion of each return movement of the carriagefrom the movement of the carriage.

All of the parts of the machine above described preferably havesubstantially the same construction, arrangement and mode of operationas the corresponding parts of the machine illustrated and described inthe Foothorap patent referred to above.

The mechanism for actuating the pawl actuator 34 from the carriage willnow be described. The other arm of the pawl actuator is connected by alink 52 with one end of a lever 54 secured to the rear end of a rockshaft 55 mounted in bearings in the line space frame and extendingtoward the front of said frame. The other end of said lever is connectedby a link 58 with an arm 60 secured to the rear end of a relativelyshort rock shaft 62 also mounted in hearings in the line space frame. Tothe forward end of the shaft 62 is secured an arm 64 which is connectedby means of a coiled spring 65 with the lower arm of a lever 63 pivotedto turn freely on the forward end of the shaft 62. The upper arm of thelever 68 is provided with a forwardly turned contact flange l0 which'isarranged to be engaged by a pin 12 carried at the left hand end of anactuating pawl or dog [4 pivoted on a stud 15 secured upon a plate l8forming a slide mounted on the line space frame and movable transverselyof said frame. The dog 14 is acted upon by a coiled spring 81! whichtends to swing the left hand end thereof downwardly to carry the pin 12into operative position with relation to the contact flange II! on thelever 68, the movement of the pawl under the action of the spring beinglimited by means of a pin 82 projecting from a plate 84 secured to theslide 78 in spaced relation thereto as shown in Fig. 2.

During the entire movement of the carriage, except the first part of theadvance movement and the last part of the return movement thereof, theslide 18 is held substantially in the position shown in Fig. 4. Afterthe first part of the advance movement of the carriage and during theentire return movement thereof, the dog 14 is maintained by the springsubstantially in the position shown in said figure. As the carriageexecutes the last part of its return movement, the slide 18 is moved tothe left with the carriage and through the engagement of the pin 12 onthe dog 14 with the contact flange 10 on the lever 68 the lever isactuated to impart a line spacing movement to the pawl carrier 26through the connections described. During the first part of the advancemovement of the carriage, slide 78 is moved back to the right to itsnormal position shown in Fig. 4. The slide 18'is provided with parallelguide slots 86 and 88 in which engage respectively a guide stud 90 andthe shaft 62 and. the plate is held in position on the guide stud andshaft by means of holding plates or washers 94 and 95. The movement ofthe slide 18 toward the left is stopped by the engagement of the lefthand end of a projection or beak 55 on the slide with a fixed stop 91rigidly secured to the right hand endof the rear rail 18.

The mechanism for moving the slide to the left from the position shownin Figs. 1 and 4 during the last part of the return movement of theframe forwardly or rear-w-ardly over carriage comprises a draft .rodi98' similar 11111011- s'truction and mode of 'operation toxthat shownin'Foothorap'Patent 1904;12'7, which extends trans- 'versely of the linespace frame in a :channel formed by the front face of the rearirailI0,r-and rear face of the earriage escapement track 1110.

The right hand end of the :draft rod 981'is 'connected by means of anattachingplate 'IJIIZ- tmthe slide 18. The left :hand endof the draftrodtis attached bymeans of a box nut 99 :to a ilaterally bent portion ofa guide plate IlII provided with slots 103 in which engage headed-fa'sten'ings I threaded into the carriage escapementrack, this guideplate moving longitudinally with the :draft rod during the longitudinalmovement of :said

rod. A spring 1 anchored --as one "end "to the fixed stop :91 andconnected 'a't its opposite'end to the draft rod 98 yieldingly retainsslide Wand the draft rod at their right=hand limits of travel asdetermined by contact ofthe left end'wallfof 7;"

the slot 86 with 'the guidestud 90.

The left hand end :portion of the 'draft rod 98 is provided with teethupon its upper face and upon'the draft rod aremou'nted a series ofarresters I04, 106 and I 08iof -*different heights en-,

gaging said teeth and: adjustably:arranged' on the red at differentdistances from the left hand -"end thereof. "The arrester :IM shavingthe greatest height and located nearest the left hand end *of the draftrod is'arranged 'to 'be' engaged'day then abutment plate 'I I0 securedto the carriage .to arrest the carriage at the end of *a f'ull zreturnmovement thereof. The arresters' IIJB-an'd1 08 are arranged to "beengaged alternatively by means of a check stop I I2 mounted 'onthecar-:

riage and protrudable todifferent-positi'ons to engage selectively thesaid arresters at "different points in the return "movement "o-f'thecar-riage. Thus the return 'movement "of the carriage "will be arrestedwith the carriageindifferent-posithereby carrying the s1ide"18'therewith and the carriage is finally arrested bythe engagement of theprojection 95 on the slide with the s'top' 9l which arrests the movementof'the-slide and the draft rod. During-this movement of the slide'theline space mechanism is actuated through the mechanism described toimpart a 'movem'ent' to the line space frame. I

When a' line space movement'- hasbeeni imparted to the line space frame,the movement ofthe frame is stopped by the *engagementof the line spacepawl '28 with the stop pin 48 to prevent overrunning of the frameandthe-frame is locked by the engagement ofthe pawlwith the toothedwheel 26. As is well-known to fthosefamiliar with this type ofmachine,'it is desirable tyunloc'k or release immediately the line'spaceframe atthe very beginning of the advance movement of the carriage. Withthe present construction the dog 14 is lifted to disengage the pin 12"from'the lever 68 during the first escapement"movementofthe carriage.

The present'machine is'provided'with' theusua1 power actuated mechanismcontrolled by apair of spaced knee levers "for-moving the Iinespace of*a lever :pivoted :on the shaftBZ. carrier .is normally held in theangular :position :Since :mechanism .may be throwniinto :opera- 'on theshaft :shown in Figs. 1 and 4.

The sleeve I44 is moved longitudinally of the shaft I4Ito engage and disengage the carriage return clutch by means of acarriage return bail and connections between the same and the sleevehaving substantially the same construction, arrangement and mode ofoperation as the corresponding mechanism shown and described in theabove Foothorap patent. The mechanism for shifting the carriage returnbail to throw the carriage return mechanism into and out of operationand the mechanism for protrud ing the check stop II2 to differentpositions to engage selectively the arresters I 06 and I 03 preferablyhave the same construction, arrangement and mode of operation as thecorresponding mechanisms illustrated and described in the copendingapplication of Oscar J. Sundstrand, Serial No. 149,571 filed June 22,1937.

The power actuated mechanism for moving the line space frame forwardlyand rearwardly over the platen comprises driving connections between theshaft I4 and the shaft I M for driving the shaft I4 in oppositedirections. The means for driving this shaft I4 includes a control shaftI41 mounted in suitable bearings carried by the side members 8 of theline space frame and by the bracket I32 and having a pinion I48 fixedthereto which meshes with a gear I49 secured to the shaft I4. The drivemechanism is controlled to drive the shaft I4 in opposite directions byshifting the control shaft I41 in opposite directions longitudinally inits bearings, the pinion I48 being a wide pinion to maintain constantmesh between said pinion and the gear during the longitudinal movementof said shaft.

The mechanism for driving the control shaft comprises a double facedclutch member I50 fast on the control shaft near its inner end andarranged to engage alternatively two coacting oppositely facing clutchmembers (not shown) secured respectively to the opposed beveled gears IIand I52 loose on the control shaft and in constant mesh with a crowngear I53 fast on the forward end of a countershaft I54 journaled insuitable bearings carried by the bracket I32 and arranged below andsubstantially parallel with the carriage return shaft I4I. A gear I55attached to the countershaft I54 adjacent its rear end meshes with agear I56 secured to the rear end of the carriage return shaft I 4|.

The control shaft I41 is moved in opposite directions to engage thedriving mechanism to cause said shaft to be driven either forwardly orrearwardly by means of knee levers I62 and I64 secured respectively torock shafts I66 and IE8 mounted 'in bearings attached to the platenframe of the machine. The movement of either of the knee levers rocksits shaft and with it an arm I fast on the shaft near its rear end, oneof which arms is embraced between spring connected centering members I12loose on the shaft and tending to maintain each of the shafts at anintermediate point between its limits of travel through the engagementof said members with a stud I14 fixed to the platen frame. The pivotedmembers I12 also engage the pin I16 secured in the adjacent arm I10thereby maintaining the platen frame.

arm centered with relation to the pin I14 on the frame. A link I18connects the two arms I10, and a second link I80 connects one of thearms with an arm fixed to a rocker I82 pivoted at I84 upon bracketsprojecting laterally from the Mounted on upwardly projecting arms onthis rocker is a bail I86 forming a rail along which rolls aperipherally grooved wheel I88 loose on the axially shiftable controlshaft I 41, but held from axial movement relatively thereto.

The knee levers I62 and I64, when rocked outwardly, respectively, shiftthe control shaft I41 axially in opposite directions to engage one oranother face of the double clutch I50 with the proper coacting clutchmember on bevel gears I5I and I52 to cause the motor to drive thetraction shaft I4 and the traction gears I49 in one direction or theother and advance or retract the line space frame and the key carriagerelatively to the operator seated in front of the machine.

When the line space frame is in operating position on the side rails ofthe platen frame, the control shaft I41 is held in central position bymeans of the pivoted centering members I12. Inrorder to hold said shaftin central position when the line space frame is lifted from the platenframe, as i often done for certain purposes, a second centering deviceacting directly on said shaft is provided. To this end a collar I90 isfixed to the control shaft I41 and is provided with a radially extendingflange I92 which of the control shaft I41.

engages in a slot in the rearwardly extending arm of the centering leverI94 pivoted on a stud I96 secured in a bracket I98 mounted on the linespace frame. A pin 200 attached tothe forwardly extending arm of saidlever projects upwardly through a slot in. the bracket I98 and isengaged upon opposite sides thereof respectively by the forwardlyextending arms of the bell crank levers 202 also pivoted on the studI96. These bell crank levers are acted upon by the respective coiledsprings 204 which tend to maintain the same in engagement with the pin209. The said'arms of these bell cranks are also arranged to engage theopposite sides of a fixed pin 206 projecting upwardly from the bracketI98.

The position of'the c'am carrier II4 about the shaft 62 is controlled bythe position of the lever I94 which in turn is controlled by theposition The connections between the lever I94 and the cam carriercomprise a bell crank lever 208 pivoted on a stud 2I0 secured in theline space frame and a link 2I2 connecting one arm of the bell crankwith the forwardly extending arm of the lever I94. The bell crank lever208 is provided with a slot 2 I4 in the other arm thereof, in whichengages a pin 2| 6 secured in an arm 2I8 adjustably fixed to the camcarrier, by means of a bolt 220.

Through the connections described, when the power actuatedmechanism formoving the line space frame is out of operation, the cam carrier is heldsubstantially in the position shown in Figs. 1 and 4. Assuming that theparts are in the positions shown in Fig. 5, as at the end of a returnmovement of the carriage, when the control shaft I41 is moved to theright to throw in the power mechanism to move the line space frameforwardly, the cam carrier is swung, in a 10. When the co'ntrol shaftHlis moved toth'e left to throw in the power mechanism to m'ove the linespace-frame rearwardly, the cam carrier I I4 is swung. in acounterclockwise direction about the shaft 62 and the actuator-dog 14 isswung upwardly to break said connection by the engagement of the camface 24 on the dog I22 with the pin H8.
